Abstract

PURPOSE:To prevnt the beautiful appearance of a finisher from being deteriorated even if arranged continuously to a combination lamp by installing a metal thin- film layer which permits the penetration of a part of light and a reflection surface arranged, keeping an interval between the metal thin-film layer, onto the back surface of a lens finisher. CONSTITUTION:A finisher 1 is installed onto a chassis continuously to a combination lamp 2 and used as decoration parts. The light which penetrates through a lens finisher 4 in the X-direction reaches a metal thin-film layer 12, where a part of the light is reflected and penetrates through the lens finisher 4 again in the reverse direction, and the residual part penetrates through the metal thin-film layer 12 and is reflected on a reflection surface 15, and a part of the reflected light is reflected again and the rest penetrates through the metal thin- film layer 12. Therefore, the reflected light by the metal thin-film layer 12 and the reflected light by the reflection surface 15 exist in mixed state, and also reflection path is made complicate, and therefore the deep color having metallic tone as that of a combination lamp 2 can be obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a decorative finisher attached to a vehicle.
1. This invention particularly relates to a finisher having a transparent (including colored transparent) synthetic resin molded product that is attached to a vehicle body in combination with a combination lamp such as a stop lamp.

[Conventional technology]

FIG. 1 is a front view showing a finisher and a large futuristic lamp installed in an automobile, FIG. 2 is a cross-sectional view taken along line AA, and FIG. 3 is a cross-sectional view taken along line B-B of a conventional finisher. In the drawings, 1 is a finisher, and 12 is a combination lamp, both of which are attached to the rear of the vehicle body.

As shown in FIG. 2, the finisher 1 includes a finisher body 3 attached to a vehicle body panel and a lens finisher 4 attached to the outer surface of the finisher body 3. The finisher main body 3 is molded from synthetic resin, metal, or the like so as to have an internal space, and the portion exposed on the outer surface is finished in any decorative color by painting or the like.

The lens finisher 4 is made of a red-colored transparent synthetic resin molded product having a smooth outer surface 4a and an inner space 6 formed on the back surface in such a manner that a large number of peaks 5 called diamond cuts intersect with each other. The protrusion piece 4c protruding from the side portion 4b is inserted into the attachment hole of the finisher main body 3, and is attached by heating and melting it to form a heat caulking portion 4d.

Combination lamp 2 is lens finisher 4
It consists of a lens 7 having almost the same structure as , a housing 8 formed in the shape of a bowl, a bulb 9, and a magnifying lens 10 made of a thin Fresnel lens. Like the lens finisher 4, the lens 7 is made of a red transparent synthetic resin molded product, and has a diamond-cut peak 5 formed on its inner surface. The housing 8 is formed into a substantially bowl-like shape from ordinary general-purpose plastic so that the inner surface forms a parabola, and a light-reflecting reflector plate 11 such as an aluminum plate is formed on the inner surface.

[Problem that the invention seeks to solve]

In the above configuration, if the finisher 1 and the combination lamp 2 are installed adjacent to each other on the vehicle body as shown in Fig. 1, when the bulb 9 of the combination lamp 2 is not lit, such as during the daytime, when looking at them, the lens A difference in color tone is observed between the finisher 4 and the combination lamp 2. In this case, lens finisher 4
In this case, the light transmitted in the X direction is reflected on the finisher main body 3 behind, and passes through the lens finisher 4 again to be visually recognized, so the color tone of the finisher main body 3 is recognized. In this case, the light transmitted through the lens 7 in the Y direction is bent by the magnifying lens 10, reflected by the reflection plate 11, and transmitted through the lens 7 again to be visually recognized, so that a metallic and deep color tone is recognized.

As described above, in the conventional finisher 1, a problem arises in that different color tones are recognized depending on the depth behind the lens finisher 4 and the lens 7, the presence or absence of the magnifying lens 10 and the reflector, the type, etc., which significantly impairs the aesthetic sense. There was a point. To solve this problem, if the interior of finisher 1 is made to have the same configuration as combination lamp 2,
There are problems such as an increase in the number of parts and the need for space for them.

This invention is intended to solve the above problems, and by forming a specific metal thin film layer on the back surface of a transparent lens finisher and arranging light reflecting surfaces at intervals, it is possible to achieve the same effect as that of a combination lamp. It is an object of the present invention to provide a finisher for a vehicle that exhibits a color tone and does not impair its aesthetic appearance even when placed adjacent to a combination lamp.

[Means for solving problems]

This invention provides a lens finisher molded from a transparent synthetic resin, a metal thin film layer formed on the back surface of the lens finisher to such an extent as to transmit a portion of light, and a distance between the metal thin film layer and the lens finisher. A vehicle finisher is characterized in that it includes a reflective surface arranged in a manner similar to that of the present invention.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

FIG. 4 is a sectional view corresponding to A--A in FIG. 1 showing an embodiment of the present invention, and FIG. 5 is a cross-sectional view of section C thereof.

The same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts.

The basic structure of the finisher 1 is the same as that of the conventional one, but the back side of the lens finisher 4 is coated, and a transparent top coat layer 14 is formed thereon.The metal thin film layer 12 is vacuum-deposited. The metal thin film layer 12 is formed using metals such as aluminum and chromium to a thickness of about 50 to 300 mm by vacuum metallizing such as , sputtering, and ion blasting. In this method, a base coat layer 13 is formed using a clear paint on the lens finisher 4, a metal thin film layer 12 is formed on the base coat layer 13, and a top coat layer 14 is further formed on top of the base coat layer 13 using a clear paint.

The finisher main body 3 also includes a lens finisher.
A reflective surface 15 is formed on the surface opposite to the metal thin film layer 12 with a distance therebetween. The reflective surface 15 is made of a coating layer containing a reflective material such as fine aluminum powder so that light is diffusely reflected, and is formed by a coating of silver paint containing a reflective material, but is not made of a metal thin film layer or the like. It's okay. In the embodiment, the reflective surface 15 is formed on the entire surface of the finisher main body 3, and is formed as a decorative coating layer 16 on the exposed surface other than the surface facing the lens finisher 4, and on the peripheral portion, another coating layer is formed on the exposed surface. 17 is formed, but it may be formed only on the surface facing the lens finisher 4.

The other configurations are the same as those in FIGS. 1 and 2.

FIGS. 6 and 7 are partial sectional views showing other embodiments. In FIG. 6, the base coat layer 13 is omitted and the metal thin film layer 12 is directly formed on the lens finisher 4.
A top coat layer 14 is formed thereon. In FIGS. 5 and 6, the top coat layer 14 is not necessarily required and can be omitted. FIG. 7 shows a joint structure suitable for omitting the base coat layer 13 and top coat layer 14, in which a sealing material 18 is interposed at the joint between the finisher main body 3 and the lens finisher 4, forming a seal structure. There is.

In addition, although the above embodiment shows the case where the lens finisher 4 is attached to the finisher main body 3, the present invention can be similarly applied even when only the lens finisher 4 is attached directly to the vehicle body panel. Further, the lens finisher 4 may be colored and transparent or colorless and transparent. Further, the surface of the lens finisher 4 may be subjected to a hardening film treatment in order to improve scratch resistance and weather resistance.

[For production]

The finisher 1 configured as described above is attached to the vehicle body adjacent to the combination lamp 2 and used as a decorative part, like the conventional finisher. In FIGS. 4 and 5, the light that passes through the lens finisher 4 in the X direction reaches the metal thin film layer 12, where it is partially reflected and passes through the lens finisher 4 in the opposite direction,
The remaining portion passes through the metal thin film layer 12 and is reflected by the reflective surface 15.

The reflected light is again divided into what is reflected by the metal thin film layer 12 and what is transmitted.

In this way, the light visually recognized from the outside is transmitted to the metal thin film layer 12.
The light reflected by the reflection surface 15 and the light reflected by the reflection surface 15 are mixed,
The path of reflection is also complicated, and since a distance is maintained between the metal thin film layer 12 and the reflective surface 15, the combination lamp 2 which has the reflective plate 11 and other parts inside.
You can obtain a deep color tone with the same metallic tone.

Similar color tones can be obtained in Figs. 6 and 7;
The illustrated embodiment is suitable when the lens finisher 4 is made of a material on which the metal thin film layer 12 can be directly formed. In addition, in the case shown in FIG. 7, the sealing material 18 prevents water from entering the back surface of the lens finisher 4, so the base coat layer 13
And even if there is no top coat layer 14, the metal thin film layer 1
2 can be kept stable.

〔Effect of the invention〕

According to this invention, a metal thin film layer is formed on the back surface of the transparent lens finisher, and reflective surfaces are arranged at intervals, so that it exhibits the same color tone as the combination lamp and can be placed adjacent to the combination lamp. It does not lose its beauty even in the most severe cases. Furthermore, even if water droplets or dirt enter the back surface of the lens finisher, they will not be visible from the outside, and the sealing mechanism can be simplified.
